Abstract:
Abstract Purpose Reducing chemical pressure on human and environmental health is an integral part of the global sustainability agenda. Guidelines for deriving globally applicable, life cycle–based indicators are required to consistently quantify toxicity impacts from chemical emissions as well as from chemicals in consumer products. In response, we elaborate the methodological framework and present recommendations for advancing near-field/far-field exposure and toxicity characterization, and for implementing these recommendations into the scientific consensus model USEtox.

Humans are exposed to several chemical substances during their regular daily activities that can be harmful even in low quantities. Accounting for the mass of a given released chemical may not be appropriate for the assessment of its toxicological impact. To overcome the lack of a systemic perspective of mass-based assessments, methods such as the chemical footprint (ChF) are an alternative to account for a given chemical’s environmental and human toxicological impacts, a task that is considered essential in order to achieve the Agenda 2030 for sustainability.

Abstract Chemical pollution is a problem of global importance. Substances of main concern of chemists worldwide are heavy metals. Heavy metals, such as copper (Cu), nickel (Ni), lead (Pb), vanadium (V), etc., can pose a serious hazard to the environment and human health. Heavy metals are toxic even at very low concentrations. The methodology, described in this paper, considers a migration of chemical pollutants in the environment, in conjunction with the approach used in the Russian regulatory system.

Abstract:
The use of chemicals in the textile industry has been widely investigated. This study used an improved method with the USEtox model to assess the environmental impacts of chemical pollutants discharged by the textile industry. The environmental impacts attributed to the discharged chemical pollutants were ranked using a quantity analysis method and a toxicity analysis method. The rankings of the two methods were compared by calculating Spearman’s correlation coefficients and outliers. The results showed that the human health and ecological hazards potential were mainly caused by heavy metals.

The severe competition in the market has driven enterprises to produce a wider variety of products to meet consumers’ needs, a strategic business system allows more effective communication among different groups at dispersed locations to share ideas and access information needed for developing new productsand executing innovative processes. The mainfunction of mobile vendor product development is to develop an attractive system which ensures customer satisfaction. Therefore, one of the important topics of the system developments is to take customer requirements into consideration.Quality fun

In this paper, we generalize the properties of the correlation matrix implied bya recursive path model using the Finite Iterative Method into the covariance case wherevariables are no more supposed to be standardized. We demonstrate that the implied co-variance matrix computed using the Finite Iterative Method is affine with respect to themodel parameters. Moreover, many other properties derive from this affinity and will be usedto simplify the computation of the first as well as the second derivatives of the UnweightedLeast Square Function used as an objective function in the estimation of th

Abstract:
The configuration of Tandem Cylinders is a typical one in researching noise and interactions between different components, where the distance-diameter ratio is a very significant parameter with which the flow form varies a lot. To clearly research the ratio's effect on tandem cylinders flow as well as the unsteady flow physics, a reduced-order model is built where Proper orthogonal Decomposition(POD) is usedto extract reduced basis modes, and Kriging model is used to train sample data and interpolate projection coefficents for each reduced basis.

Abstract:
A hybrid approach consisting of two neural networks is used to model the oscillatory dynamical behavior of the Kuramoto-Sivashinsky (KS) equation at a bifurcation parameterα=84.25. This oscillatory behavior results from a fixed point that occurs atα=72having a shape of two-humped curve that becomes unstable and undergoes a Hopf bifurcation atα=83.75. First, Karhunen-Loève (KL) decomposition was used to extract five coherent structures of the oscillatory behavior capturing almost 100% of the energy. Based on the five coherent structures, a system offive ordinary differential equations (ODEs) wh

The Young’s modulus of MWCNTs/MnO2nanocomposites was determined using analytical models include Voigt and Reuss bounds, Hashin and Shtrikman bounds, Halpin–Tsai model, Hui-Shia model. Voigt upper bound, Halpin-Tsai and Hui-Shia models predict nearly same Young’s modulus of MWCNTs/MnO2 nanocomposite in longitudinal direction.

Large-scale wireless sensor networks (WSNs) have demonstrated some complex features which are similar to those of other types of complex networks, such as social networks. Based on these complex features, evolution process and characteristic of WSNs, we represent a WSN topologically by building a suitable model, which is named as the reliability-oriented local-area model (ROLM) and aimed at improving the performance of WSNs. For analyzing the performance of the ROLM, we define the reliability as the probability of that the relative error between the measurement and the true value is equal to o
